Finger touch on a touchscreen is detected by technologies embedded in in the handset, and the location of touches within the display area acts as an input device like any keyboard or mouse, to interact with menu of the phones. Successfully infusing a man’s first sense of touch to a machine requires a lot of technologies to be applied , including resistive principle,surface acoustic wave technology, capacitive technology,strain gauge, optical imaging, dispersive signal technology, etc.

Resistive touch panel contains many layers sandwiched by thin space that act as a medium to pass on the touch sense. sharp objects can damage the layers which are otherwise water and dust resistant. surface acoustic wave technology’s ultrasonic wave help pass the touch sense.

Due to arrive in the New Year here in the UK via Vodafone, Nokia’s relatively new N900 Maemo mobile phone tablet gets turned into a controller for the PlayStation 3 game console. The hack in question is in fact a new application currently still being improved and is in its early stages. Its known as BlueMaemo Bluetooth emulator and allows the N900 to mimic bluetooth devices.

If you’re a Nokia fan and happen to have the PS3, this doesn’t look too complicated to setup which means this application could make your gaming experience even cooler.

Its developer Valério Domingos humbly points out that the purpose of connecting up to a PS3 is purely for menu navigation and easier text input, though we’ve no doubt a few hardcore Nokia loyalists will try using this in an action game to prove the N900’s superiority.

Unfortunately, the video is in Italian but you should still be able to make out most of what is happening during the entire process. Please note that BlueMaemo is still in the extras-devel repository, this means that theapplication is still in alpha and unstable and may hang/crash your device.

What was first unveiled exclusively on the Motorola Droid is now available to the rest of the Android gang. If you’ve got an Android phone running version 1.6, you’ll be able to download the new Google Maps Navigation application for free off the Android Market from today.

Android 1.6 phones in the US currently include the currently available T-Mobile my touch 3G, the G1 and the HTC Tattoo, as well as the Sony Ericsson Xperia X10. However handsets like the HTC Hero, Droid Eris, Samsung Moment and the Samsung Behold II all run Android 1.5 so won’t be getting the new feature.

While you will get features like turn by turn voice guidance and automatic rerouting, some features of Android 2.0 are not available on Android 1.6, for example, the ability to use the “navigate to” voice command. Nevertheless, if you’re an Android user with the eligible phones mentioned above in the US, you’re definitely in luck and the likes of TomTom, Garmin will no doubt be banging their heads against the wall with this news. If you’re in the UK / non-US, it looks like there could be an unofficial way to get this working on your Android phone, this will mean abit of tweaking around but watch this space.
